Alpine RSW10D4 Shallow Subwoofer in Proline X Micro Series Enclosure

The Alpine RSW10D4 Proline X Micro Series combination represents the pinnacle of space-efficient bass solutions for modern vehicles. This Alpine RSW10D4 shallow subwoofer delivers exceptional 600W RMS power handling in just 3.25 inches of mounting depth, paired with a precision-engineered Proline X Micro Series enclosure that maximizes performance while minimizing space requirements. The result is a bass system that fits where traditional subwoofers cannot, without compromising the hard-hitting performance that enthusiasts demand.

Shallow-Mount Innovation for Maximum Flexibility

The Alpine RSW10D4 features groundbreaking Gen2 DD-Linear Magnetic Circuit technology that enables remarkable 20mm cone excursion - matching the performance of full-size R-Series subwoofers. The oversized 4-inch voice coil, powered by a neodymium magnet, generates substantial air movement despite the compact profile. This innovative design allows installation in tight spaces like under seats, in compact vehicles, or shallow trunk installations where depth clearance is limited.

Premium USA-Made Enclosure Engineering

The Proline X Micro Series enclosure exemplifies American craftsmanship with precision CNC-cut construction and meticulous attention to acoustic optimization. Each enclosure undergoes rigorous quality control to ensure perfect air-tight seals and optimal internal volume for the Alpine RSW10D4's specifications. The compact design maximizes bass output while requiring minimal vehicle space, making it ideal for daily drivers who need cargo room without sacrificing audio performance.

Professional-Grade Performance and Reliability

This combination delivers impressive frequency response from 29Hz to 200Hz with exceptional clarity and precision. The die-cast aluminum frame provides rigid support that minimizes unwanted resonance, while the lightweight aluminum dust cap enables quick sound transitions with minimal distortion. The dual 4-ohm voice coil configuration offers flexible wiring options for 2-ohm or 8-ohm total impedance, ensuring compatibility with various amplifier configurations.
